This whole page is generated from plan.yml and meetings.yml — Outline and For Next Meeting come from plan.yml; WikiGroup Contributions ships as a template students complete on Moodle. Regenerating is always safe. Paste it into the wiki once per meeting; after that, student edits live on Moodle and are never overwritten.

Body of Knowledge

GIT / Fundamental Concepts

Topics

1. Uses of computer graphics and interactive techniques and their potential risks and abuses.

a. Entertainment, business, and scientific applications: e.g., visual effects, generative imagery, computer vision, machine learning, user interfaces, video editing, games and game engines, computer-aided design and manufacturing, data visualization, and virtual/augmented/mixed reality

b. Intellectual property, deep fakes, facial recognition, privacy(see SEP-DEIA, SEP-Privacy, SEP-IP, SEP-Professional-Ethics)

2. Graphic output

a. Displays (e.g., LCD)

b. Printers

c. Analog film

d. Concepts

i. Resolution (e.g., pixels, dots)

ii. Aspect ratio

iii. Frame rate

3. Human vision system

a. Tristimulus reception (RGB)

b. Eye as a camera (projection)

c. Persistence of vision (frame rate, motion blur)

d. Contrast (detection, Mach banding, dithering/aliasing)

e. Non-linear response (dynamic range, tone mapping)

f. Binocular vision (stereo)

g. Accessibility (color deficiency, strobing, monocular vision, etc.)(see SEP-DEIA, HCI-User)

Learning Outcomes

1. Identify common uses of digital presentation to humans (e.g., computer graphics, sound).

2. Describe how analog signals can be reasonably represented by discrete samples, for example, how images can be represented by pixels.

3. Compute the memory requirement for storing a color image given its resolution.

Name for this page

Paste this as the Moodle wiki page title, so the name matches the [[links]] that point here.

Copy this into the Moodle wiki page

Whole page for the first paste. After that, pick one top-level section and paste it through Moodle's edit link for that section, so the rest of the page (including student edits) is left alone.

Please **do all of your editing here in the wiki** — not in a document you paste in at the end. The wiki keeps a full page history, so working here is what lets your contributions be recognized.
Only edit within this **WikiGroup Contributions** section.

For Creole wiki syntax, please see the [[https://docs.moodle.org/502/en/Creole_format|Moodle Creole Format documentation]]

Make sure that you use your [[Personal Wiki Page|Personal Wiki Page (PWP)]] to sign your contributions.

== Edited Transcript with Captioned Photos ==
//**Instructions — delete this block once your section is written.**\\
**1.** Start by copying the photos-and-transcript page linked under "Post-Meeting Resources" above and paste it here. Tidy the transcript into readable prose (fix obvious errors, correct spelling, drop fillers, and remove comments not pertinent to the meeting).\\
**2.** Move each photo, together with its **Caption:** line, from the top of this section to where it fits the discussion. Replace the TODO text on the Caption line with a description of what is on the board in that photo (the text after the pipe (|) in the image markup is only hidden alt text and will not appear on the page). If something in the photo(s) or the transcript is not clear, add your question as an action item for Dr. Hepting.\\
**3.** Link mentioned and other helpful URLs.//

**Contributors' PWPs:**


== Action Items for Dr. Hepting ==
//**Instructions — delete this block once your section is written.** List anything Dr. Hepting agreed to follow up on or questions that came up during your edits to the meeting record, one bullet each.//

**Contributors' PWPs:**


== Commentary and Discussion ==
//**Instructions — delete this block once your section is written.** Add your group's reflections: what was confusing or surprising, how today connects to earlier meetings or other courses, and any questions worth raising next time. Two or three substantive points is plenty.//

**Contributors' PWPs:**


== Fair Exam Questions (with Answers) About Today's Meeting ==
//**Instructions — delete this block once your section is written.** Write two or three exam-style questions a fair exam could ask about today's material, each with an answer. Aim to test understanding.//
